Kosada, as creator of Vuo, owns copyright on the Vuo Core (compiler, editor, and built-in node sets). Kosada also owns the Vuo trademark.
Things you make using Vuo — compositions, node sets, compiled applications, generated images — are all yours. You own copyrights.
In order to make contributions to the compiler and core node sets, licensing requires that the copyright of contributions be transferred to Kosada — so that we may incorporate your contributions into Vuo. (This enables Kosada to act as the single legal steward of Vuo — so that we may enact the license cascade, and so that you, as a contributor, will be shielded from potential legal action taken against Vuo.)
